Just so we're not gambling we went ahead and hacked /modules/mod_rokminievents3/tmpl/default_item.php inserting a str_replace to replace the offending URL portion with nothing around the middle of the code.
<?php if (!$event->getLink()): ?>
<span class="rme-title"><?php echo $event->getTitle(); ?></span>
<?php else: ?>
<?php
$values = $event->getLink();
$internal = $values;
$link = $values;
$link = str_replace("modules/mod_rokminievents3/", "", $link);
?>
<a class="rme-title<?php echo $internal ? '' : ' rme-external-link'; ?>" href="<?php echo $link ?>"><?php echo $event->getTitle(); ?></a>
<?php endif; ?>
Naturally we'd prefer a fix.
